Robust ontology acquisition from machine-readable dictionaries.

In this paper, we outline the development of a
system that automatically constructs ontologies by
extracting knowledge from dictionary definition
sentences using Robust Minimal Recursion Semantics
(RMRS), a semantic formalism that permits
underspecification. We show that by combining
deep and shallow parsing resources through
the common formalism of RMRS, we can extract
ontological relations in greater quality and quantity.
Our approach also has the advantages of requiring
a very small amount of rules and being
easily adaptable to any language with RMRS resources.
